when will the leaning tower of pisa collapse? many world famous monuments are risk. you to climate change war and negligence. but with the help of 3 d scans, drones and a i, we can save these eye clinic buildings, at least virtually how it works. that's our topic on ship today. ah. having digital backups comes in handy, like of your diploma or your favorite. todos the same is true for historic buildings that have deteriorated over the years, like mexico cities famous metropolitan cathedral, which has been damaged by several earthquakes. luckily it's 3 d model is earthquake proof. that's also a detailed 3 d model of the gateway of india and moon by which has been eroded by sea water. but it's estimated at so far, only about 15 percent of the world's casual heritage has been digitally preserved

by now. ukraine's cause will have it. it is especially at risk. it's not only buildings and gods as that in danger. but all kinds of online archives of things like paintings and lid, which are to me, in ukraine. russian bombs are not only killing people and decimating homes and infrastructure. they're destroying cultural heritage to me. right now everything's at risk. everything from physical museum collections to records of library holdings, to servers with web sites. at the end of the day, the internet is as physical as, as anything else that depends on servers that have to be connected to power and connected to cables. and those servers are at risk of being destroyed. if servers are destroyed, digital backups of art and other records their last to. that's why quin number ski and a group of librarian 3 searchers and programmers joint forces to start suture saving,

ukrainian cultural heritage online. soon after the russian attack, such a volunteers began archiving as much as possible relying in what they could find from ukrainian cultural institutions online. we're trying to, to capture those websites with everything that's on them. any pdf, any image, any 3 d model, or, or walkthrough, or trying to capture a version of, of all of it so that, that can be, you know, something that is safe and outside the country. ah, some tech companies are supporting search by providing servers in storage for free so far, the group has saved more than 30 terabytes of content from over 3500 websites. more than 1300 volunteers helped with the task. sometimes it's not even like a firefighter squad, it's, it's more like, you know, neighbors with water buckets. you know it, many of us had not really done any work on web archiving. before this quin

dombrowski hopes to chose, archive will never actually be needed. we, we don't actually want these to be useful if they're useful. it is a sign that something terrible has happened in terms of the preservation of, of cultural heritage. the great thing about this project, anyone can pitch him. you can learn more at social dot org. sometimes doing your part to digital to preserve cultural heritage is simple. other times more expertise is needed. ah, the great wall of china is the world's longest manmade structure. it's more than 20000 kilometers long over 2000 years old and in desperate need of repair. droves are used to survey ports of the wall that are difficult to access. after filming the wall of close, the data is the used to create 3 d models. a i is then used to scan these models, identified the damage, and plug the necessary repairs. the non profits cy arc specializes in 3 d

laser scans of endangered cultural sites. here's how it works. the laser scanner sensors pulses of light by measuring how long it takes for the lights to be reflected off various surfaces. it's possible to determine the size and surface material of objects. this method is called lighter. another technique that's used as photo grammar tree, where overlapping photos a combined to create extremely realistic 3 d models. anyone can check out the scans on google's arts and culture platform or download the datasets on open heritage. 3 d digital technology has become critical in reconstructing destroyed buildings. in august 2015, the temple of balcony and palmera syria was reduced to rubble by the islamic state

. terrorist group. however, back in the 1950s. smith's archaeologist to po colors, excavated undocumented the temple. the information collected back then made it's possible to create a virtual reality image and 3 d model or the temple of bounce. yameen is supposed to be rebuilt, just like pun mirrors, arch of triumph, which was also destroyed by ins. using digital muddles, robots built a smaller replica of the archway which has been exhibited in several cities. hopefully, the arch of triumph can one day return to its original location in syria. in 2019 of fire destroyed large parts of the not sure, a dam cathedral. the incident shot france and people worldwide business me in one of the most iconic landmarks in paris was lost forever. fortunately not, it's the beam restored. true to the original thanks. in part with this man,

andrew tell him no tra, dom was a lifelong passion for andrew talon. here the belgian born art historian is walking around the 850 year old cathedral before the fire. he was recording a $360.00 degree video, which is why the image looks a bit distorted. mother, interesting detail too about this is a bit of lead that was often used as a joint between edge that it elements such as this talon used laser scanning technology to map no to them. he collected more than $1000000000.00 data points, which he then linked to photos of the scanned areas. andrew became fascinated with the cathedral from a very young age. his work there in trying to create a global laser survey. that is really what makes his work stand out there. so we

are still reading the benefits of that effort from 2010 in 2012. he scans not as much as i'm, you know, but it does, since it's not hundreds of cathedrals from sweden to spain not turned on was i think, a crown jewel on a lot of ways. and andrew talon did not live to see exactly how important his scans would turn out to be several months before the fire destroyed notre dams. roof inspire, he died of cancer. part of the reconstruction plan is based on talent work. it is one of several records that we have of the pre fire state of neutral. and this is of course, critically important as the decision was made to restore the building identical, you know, to damage restoration, teen combine talents, models with additional scans resulting in this impressive 3 d model.

us software developer autodesk provides a cloud based data platform, which gives all the stakeholders involved in reconstruction, access to the latest records that makes it easier to plan construction, work like calculating how many oak trees need to be felt to replace notre dame's fire. frances, determined to restore the cathedral true to its original design, the one that andrew talon and his team mapped before the fire, thus safeguarding its future. there are many ways in which cultural heritage can be endangered. one prominent example art stolen by colonizers, the kenya based non profit, african digital heritage, is working to digitize these treasures. and we frame how this history is documented . yet another advantage of digital copies, cultural heritage can be showcased to a global audience online. ah,

artifacts from african history? ideally, you might see them in person in the museum collection, but kenyan historian chow tianna minor. once more world wide accessibility, we decide for many reasons, one of the primary ones being access, enabling audiences practitioners, such as to access material remotely to access material from different countries. you know, you don't have to be in kenya to access cultural heritage. another reason why we digitize is to preserve the material the digital heritage specialist trains museum staff across kenya. the teams have a huge task ahead of them, digitizing tens of thousands of books, papers, and photos. some of them hundreds of years old. i lot of the time when i'm training on digitization,

i would say read the process of digitization is not about just sticking the photograph. it's about the decisions that you make before you take this photograph . the 1st step is inspection and selection. not everything can be digitized choosing the right to objects is also a way of writing history. when we are digitizing, do we still defeat the theme? colonial kind of tom. do we still repeat the ways in which our people are objects i describe, or is this an opportunity to say okay, let's change how things are described. 0, one example. the mama comes in the 1950s. the british army and colonists detained many canyons and forced labor comes using a cable material. the african digital heritage non profit has created 3 these guns of the country. we've been going out into the field documenting these

sites in that kind of i would say akila, gina, sans to see what struck to and still exist as well as contextualizing this tangible heritage, dis, tangible, nato buildings in land to people as memories and people stories digitizing african cultural heritage is a way to re examine, contextualize, and preserve this history and culture. ah, i feel that they walk back, read, going to digitize his see is also about connecting time. we are connecting the path to the present. and in this very act we are shipping future. 7 thanks to digitization, it's possible to save, got casual heritage for generations to come back. 3 d models shouldn't be regarded as mere replacements or backups of the originals. instead, there a chance for people across the globe to get to know cultural sides they otherwise

may have never seen was your take? can monuments really be capital on the screen? or do you need to physically be there to get the full experience? let us know what do you think? as often now, bye bye. ah . the double used crime fighters are back africa most successful in radio drama series continues this season. the stories focus on hate speech, color of prevention, and sustainable charcoal production. all episodes are available online, and of course you can share and discuss on d, w, africa's facebook page, and other social media platforms, crime fighters,

tune in now. people in trucks injured one, trying to flee the city center. more and more refugees are being turned away. order families on the reason for the credit on we located demonstrate people seeing extreme dreams. ross getting 200 people. hassan from the jews b, around the world. more than 300000000 people are seeking refuge. yes, the wine because no one should have to flee. make up your own mind d. w. made for mines were .
